The solid state disk is easy to cause damage to a physical boot area under an abnormal operating environment, so that the solid state disk cannot normally enter a normal boot mode, which is commonly called 'brick change'. At this time, the shell must be opened, and a corresponding repair instruction or signal is sent to a specific control pin (i.e., a code guide pin for forced curing) of the main control module, for example, the control pin of the main control module is shorted to make the control pin set to a low level (i.e., the control pin of the main control module is directly shorted to a ground line in a manual manner by a metal tweezers), and the control pin is forced to enter a cured initialization guide mode (i.e., a repair mode) inside the main control module, so that the drive letter can be found, and then the repair is performed by special volume production software.
When the existing solid state disk product has the phenomenon of brick change, the existing solid state disk product firstly needs to return to a factory, then a professional technician dismantles a shell, and a main control designated position is in short circuit to carry out forced repair. Because the shell is generally a metal part, the shell is easy to damage after being disassembled and cannot be used any more, the price and the proportion of the shell in a product are quite high, the gross profit of a consumer product is not high, various costs, particularly the costs of manpower and time, can be increased when the consumer product returns to a factory, and therefore a certain improvement space exists in the existing solid state disk repairing mode.

TABLE 1
In this embodiment, PIN5 (PIN 5 of the power interface) in the table is used as a redundant ground line, i.e., the signal line 6. As shown in fig. 5, the specific flow is described as follows:
after the solid state disk is powered on, the auxiliary module 5 firstly judges the level of a PIN 5; if the level is low, the auxiliary module 5 does not act, and the solid state disk enters a normal working mode; if the level is high, the auxiliary module 5 waits for receiving an interactive command from the PIN5 PIN, and after receiving a correct command, the auxiliary module 5 outputs feedback information through the PIN5 PIN and controls the main control module 2 to enter a repair mode; when the main control module 2 enters the repair mode, the repair module in the repair device 7 starts a repair program to repair the main control module 2.
